)Themes
When using a plot generator object, it is possible to specify one of three output themes: light, dark and current.
light theme
The light theme produces plots with a white background and a black foreground color. This is the default theme:
dark theme
The dark theme produces plots with a black background and a white foreground color.
op = Obsplot(theme="dark")
op(
{
"y": {"grid": True},
"color": {"legend": True},
"marks": [
Plot.lineY(
stocks, {"x": "Date", "y": "Close", "stroke": "Symbol", "tip": True}
)
],
}
)current theme
The “current” theme uses a transparent background and a currentColor foreground, so it should keep the current color theme:
op = Obsplot(theme="current")
op(
{
"y": {"grid": True},
"color": {"legend": True},
"marks": [
Plot.lineY(
stocks, {"x": "Date", "y": "Close", "stroke": "Symbol", "tip": True}
)
],
}
)
